After attending a series of performances of Turk in London, Karl Gottlieb von Windisch in 1784, published a series of letters in which he attempted to explain the secret of the mysterious machine. A second attempted expose of the Turk was written by Joseph Friedrich Freiherr von Racknitz (1744 - 1818) which included this speculative image of the working parts. Racknitz was wrong about both the position of the director and the dimensions of the automaton.
